B30b 15/14, 15/16; B65b 63/02 ABSTRACT OF THE DISCLOSURE A trash handling and baling system connected at the base of a vertically extending trash chute in a multistory building. The trash chute is coupled to a trash directing means having a sloped base therein. The sloped base directs the trash out of the trash directing means and into a baling means having a vertically movable compacting ram which compresses the trash into a bale. First and second time-delayed photocell control means are provided in the trash directing means and are operated when the light beams are broken by the presence of trash. The first control means operates the compacting ram and blocks off communication between the trash directing means and the baling means While the second control means blocks off communication between the trash chute and the trash directing means and signals when the bale has reached proper size.

This invention relates to a trash handling and baling system which is particularly adapted for the disposal of trash from multistory buildings such as apartment houses, ofi'ice buildings, and the like wherein an elongated trash chute is utilized.

In the usual variety of multistory building, at least one, and possibly more than one, vertically extending elongated trash chute is provided, with each floor of the building having an access opening which permits trash to be dropped or deposited into the chute. Such trash then descends through the chute by gravity until it reaches the basement or lower level. At this area, some means must be provided for either destroying the trash or otherwise disposing of the same. As used herein, the term trash is intended to comprehend garbage, waste paper, refuse, or any other form of disposable matter.

In the past, the simplest and least expensive type of installations for disposing of trash from multistory buildings involved the use of a collection pan or bin at the base of a trash chute. The trash would drop by gravity through the chute into this bin and would collect therein until a janitor or maintenance man removed the same and burnt it or placed it in suitable trash containers. This was an extremely undesirable type of arrangement, if for no other reason than the fact that the odors from the trash collected in the bin would pass back up through the trash chute and would exhaust into the upper floors of the building each time someone opened an access door to the trash chute. Additionally, a considerable amount of time and effort was required to manually dispose of the collected trash.

A more recent innovation utilized a horizontally operating pushing or compacting means which directed the trash at the base of the trash chute laterally into a specialized form of container. Once the container was full of trash, it had to be removed from the building and lifted onto a truck which removed the same.

While prior systems did represent an improvement over the arrangement wherein the trash merely collected in a bin, such systems nevertheless have not proved wholly satisfactory for several different reasons. First of all, because the trash pushing means operated horizontally and the trash receiving cart had to be disposed adjacent thereto, a considerable amount of space was required to accommodate such a system. In certain existing structures, the garbage room was insuflicient in size to accommodate such a system, Moreover, even in a new building wherein such a system was to be installed originally, it was necessary to leave an inordinately large garbage room to accommodate the system, thereby wasting space which could otherwise be used more valuably.

Another disadvantage which was found with systems of this type, was that the trash tended to become so compacted within the cart that it could not readily be removed therefrom. Still a further drawback with such a system was the fact that the heavy metal cart, fully loaded with garbage, had to be removed from the garbage room, wheeled through hallways and doors and removed from the building whereat it could be loaded onto a special form of truck. Such moving of the loaded cart often damaged the buildings walls and doors and because of the extreme weight of the cart, difficulty was encountered in moving the same. Moreover, using such a prior art form of system, it was necessary to provide a truck having a specialized form of lifting means so that the loaded cart could readily be lifted thereonto. This meant that the buildings owners or managers would not be able to utilize any trash removal company which they desired to employ, but instead, were limited to employing a trash removing company which utilized this special form of truck. This necessarily increased the cost of trash removal for the buildings. Finally, such a prior art systems required that at least one, and usually several empty carts be maintained on hand so that when one cart became full, a new empty cart could replace it. Naturally, this meant that additional space had to be provided to accommodate all of these empty carts.

With the foregoing in mind, it is, therefore, an object of the present invention to overcome the difficulties and deficiencies encountered in prior art trash handling systems and to provide in their stead, a new and improved trash handling system.

Another object of the present invention is to provide a trashing handling system wherein the trash is compressed into a self-sustaining bale which can be manually handled, packaged in a plastic container, or so on, without the need for maintaining such trash in any special form of vessel.

Another object of the present invention is to provide a trash handling and baling system which requires a minimum amount of floor space for operation, which can be readily installed in existing structures or in new structures, and which operates in a simple and etficient manner.

Another object of the present invention is to provide a trash handling and baling system which operates substantially automatically and which does not require the presence of an attendant or operator.

Another object of the present invention is to provide a trash handling and baling system which prevents objectionable trash odors from traveling up through the trash chute and exhausting onto the upper floors of a building or structure.

Another object of the present invention is to provide a safe, efiicient and relatively inexpensive apparatus for handling trash and for compressing the same into bales which can be manually handled and removed by any conventional type of trash hauling vehicle, thereby eliminating the need for any specialized type of trash receiving container or any specialized form of vehicle for handling such container.

Other objects, advantages and salient features of the present invention will become apparent from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment thereof.

Referring to the drawings:

FIGURE 1 is a perspective view of a trash handling and baling system in accordance with the principles of the present invention;

FIGURE 2 is a top plan view thereof;

FIGURE 3 is a fragmentary side elevational view thereof;

FIGURES 4a through 4d are continuous diagrammatic views showing the manner of operation of the apparatus; and,

FIGURE 5 is a schematic control circuit for the present invention.

With continuing reference to the drawings, the system of the present invention includes, in general, a trash directing means generally designated adapted to be connected to the base of a vertically extending elongated trash chute generally designated 12, a baling means generally designated 14, and first and second control means respectively generally designated 16 and 18.

The vertically extending trash chute 12 is shown in the drawings of the present invention to be circular in crosssectional configuration, but it will, of course, be obvious that such chute can be square, rectangular, or of any other suitable cross-sectional formation. The trash chute 12 itself does not form a part of the present invention, but instead, represents the conventional trash chute which is installed in every usual multistory building such as an apartment house, office building, or the like. The lower end of the chute 12 fits into an acoustical collar 20 formed of some suitable resilient or sound absorbing material so that the shock and sound of the trash dropping into the trash directing means 10 will not be transmitted directly back up through the trash chute 12. A deodorizing air collar 22 is positioned between the acoustical collar 20 and the top surface 24 of the trash directing means 10. A conventional blower 26 is connected with the air collar 22 to cause a constant downdraft in the trash chute 12. In this manner, the odors from the trash cannot escape back up the trash chute 12, but instead, such odors will constantly be forced downward toward the apparatus of the present invention. Additionally, a sanitizing chemical conditioner 27 can be coupled with the blower 26 to blow through the collar 22 into the means 10 for killing the bacteria therewithin.

Considering the trash directing means 10 in further detail, it will be seen that the top surface 24 thereof includes a central opening or aperture 28 which communicates with the trash chute 12 through the collars 20 and 22 so that the trash from the chute can drop into the trash directing means. Such directing means further includes a rear wall 30, a forward wall 32, and a pair of opposed parallel side walls 34 and 36 extending therebetween. Finally, such trash directing means includes a sloped base or bottom wall 38 which causes the trash dropping into the chute to be forwardly directed toward an outlet opening 40 formed in the forward wall 32. Thus, the various walls of the trash directing means define therewithin a trash receiving chamber 42. The trash enters this chamber through the opening 28, descends till it contacts the sloped base wall 38 and is forwardly directed therealong through the outlet opening 40.

The trash directing means is mounted upon a base plate 44 by means of internally threaded tubes 46 relatively adjustable with upstanding threaded bolts 48. Thus, by properly adjusting the bolts within the tubes, the height of the trash directing means 10 can be varied.

A horizontally slidable door 50 having rollers 52 mounted along the side edges thereof is positioned at the upper end of the trash directing means 10 with the rollers 52 being positioned in guide channels 54. As can be seen, the guide channels not only extend through the unit 10 but considerably therebeyond and are bridged at their outer ends by a cross beam 56. A solenoid 58 is centrally mounted upon the cross beam 56 with the solenoid plunger being pivotally and operatively connected to a hook type crank arm 60 which locks within a central handle 62 on the forward end of the door. A fusible link 63 is provided between the handle 62 and door 50 so that in the event of fire, the door will be released and will close to prevent further trash from entering the fire. Manual operating handles 64 are also provided at opposite sides of the door 50 at the forward edge thereof. Suitable cable means 66 are connected to opposite sides of the door 50 and these cable means extend through the upper end of the trash directing means 10 and are reeved over pulleys 68 mounted at the top of the side wall 36. Counterweights 70 are mounted at the lower end of these cables 68 with the counterweights being suitably positioned in tubular guides 72 mounted on the side 36 of the unit. Normally, the plunger of the solenoid 58 is extended so that the hook crank 60 fits within the central handle 62 of the door 50 in the manner shown in FIGURES 2 and 3. In such position, the door can be considered as retracted so that the opening 28 in the top of the trash directing means 10 remains open. However, when the solenoid plunger retracts to pivot the hook crank 60 out of the central handle 62 on the forward edge of the door 50, as is shown in FIGURE 1, the counterweights 70 descend by gravity and cause the door 50 to move into the trash directing means 10 to thereby block the opening 28 and hence block communication between the trash chute 12 and the trash receiving chamber 42. When it is desired to reset the door from such an advanced position to its retracted position, the door 50 can be manually moved outward by a pulling force exerted on the handles 64.

The control means or signal generating means 16 and 18 each take the form of a photocell and suitable light source. A time delay is incorporated in the circuit with each photocell as will be presently described. The first photocell means 16, as can best be seen from FIGURE 1, is positioned near the lower end of the forward wall 32 while the second photocell means 18 is positioned to the rear thereof and vertically thereabove. It can also be seen that the height of the second photocell means 18 is above the top level of the outlet opening means 40.

Directing attention to the baling means 14, it will be seen that the same is supported upon a base 74 having wheels 76 mounted on the underside thereof. The wheels 76 ride along a pair of spaced apart tracks 78 so that the baling means 14 can readily be moved toward and away from the trash directing means 10. The baling means 14 includes a pair of spaced parallel side walls 80 and a top wall 82 positioned vertically above the base 74. The forward wall of the baling means, which is the wall adapted to confront the forward wall 32 of the trash directing means 10, includes an inlet opening means 84 and a door 86 outwardly swingable about a hinge 88. The opposite or rear wall of the baling means includes a main door 90 swingable about a vertically extending hinge 92 and a small auxiliary door 94 at the top thereof downwardly swingable about a horizontally extending hinge 96.

A compacting means generally designated 98 is mounted at the upper end of the baling means 14. This compacting means 98 includes a cylinder 100 having a piston 102 movably mounted therewithin. The piston is carried by an elongated piston rod 104 which has mounted at the lower end thereof, a suitable compressing ram or plate 106. It will be appreciated that due to the formation of the walls of the baling means 14, an internal trash compacting chamber 108 is formed therewithin. The ram or plate 106 is of the same cross sectional configuration as this chamber 108 and is mounted for movement therewithin. A suitable opening is provided in the top wall 82 to permit passage of the piston rod 104 therethrough. Also, an additional slot 110 is provided at the forward end of the upper wall 82 so that an upstanding and vertically movable door 112 can fit therethnough. This door 112 is fiXed to the ram 106 and is movable therewith.

Before describing the manner of operation of the present invention, attention can be directed to FIGURE 5 where one suitable form of schematic operating circuit is shown. It will, of course, be understood that the particular circuit shown in FIGURE 5 is only an exemplification of a suitable circuit and it is recognized that those skilled in the art may devise other suitable similar circuits for accomplishing the same function. It can first be seen that a suitable alternating current power source is connected across a pair of electrical lead lines L1 and L2. A motor 114 is connected between these two lead lines and when a manual switch 116 is closed, the motor is energized. The motor serves to mechanically drive a pump 118 which connects through a valve 120 to the cylinder 100. A suitable hydraulic reservoir or tank 122 is provided so that hydraulic fluid can be pumped by the pump 118 through the valve 120 and to the cylinder 100 to operate the piston 102 mounted therewithin. A biasing spring 124 normally moves the valve 120 to the position whereat the hydraulic fluid from the pump is delivered beneath the piston 102 and hence the ram 106 is maintained in raised or elevated position. However, when a solenoid coil 126 is energized through operation of the photocell means 16, the valve 120 is moved to the opposite position so that hydraulic pressure is delivered above the piston 102 and so that the ram 106 descends.

The photocell 16 is connected between the powerlines L1 and L2 in series with a coil 128 which operates a switch 130. A time delay device 132, of any suitable conventional design, is incorporated in the circuit between the switch 130 and the solenoid coil 126. Thus, when the light beam from the photocell means 16 is broken, the coil 128 operates the switch 130 to close the same against a contact on the line L1. This passes current through the time delay device 132 and through the solenoid coil 126 thereby moving the valve 120 against the biasing force of the spring 124. A manual switch 134 can also be provided for the purpose of operating the valve 120 independently of the photocell means 16.

The other photocell means 18 is connected across the lines L1 and L2 in series with a coil 136 which operates a switch 138. Thus, when the light beam from the photocell means 18 is broken, the coil 136 closes the switch 138 so that current from the line L1 will pass to a time delay device 140, to the solenoid 58 which normally maintains the door 50 in its opened position and to a suitable horn or alarm 142. When the manual switch 144 in such line is closed, the photocell means 18 will thus operate the solenoid 58 and the alarm 142 after an appropriate time delay as determined by the device 140.

If attention is now directed to FIGURES 401 through 4d, operation of the present invention will be described. It will, of course, be appreciated that the details of the trash directing means and the baling means 14 have been eliminated in FIGURE 4 and that merely the basic shapes thereof have been shown so that operation of the present invention can be simply illustrated.

In FIGURE 4a, the ram 106 is in its normal elevated position and the door 50 is in its normal retracted position as shown in FIGURES v2 and 3. The baling means 14 has been placed in juxtaposition to the trash directing means 10 so that the inlet opening means 84 of the baler and the outlet opening means 40 of the trash directing means are in communicating alignment. Thus, the trash drops directl from the trash chute 12 into the trash receiving chamber 42, abuts against the sloped bottom wall 38 thereof and is directed through the openings 40 and 84 and into the internal compacting chamber 108 within the baling means. This trash gradually fills the baling means and eventually starts to back up Within the trash directing means thereby breaking the light beam of the photocell means 16, as shown in FIGURE 4a. When this occurs, the coil 128 closes the switch 130 to supply current to the time delay device 132. In operation, it has 6 been found that a suitable time delay interval for this device is 15 seconds. After such a time interval has elapsed and the photocell beam is still broken thereby maintaining the switch in a closed position, the current will pass to the solenoid coil 126 thereby moving the valve 120 against the biasing force of the spring 124.

When the valve 120 is so moved, hydraulic fluid is supplied to the compacting means 98 to act upon the upper surface of the piston 102 and hence to cause the ram 106 to descend within the compacting chamber 108 and t0 powerfully compress the trash therewithin. As the ram 106 descends, the door 112 carried thereby moves downwardly thereby temporarily blocking communication between the trash receiving chamber 42 and the trash compacting chamber 108. Thus, a small block of powerfully crushed and compressed trash is formed in the bottom of the compacting chamber.

The ram is then raised and the door 112 is likewise raised, and the trash is again flowed into the compacting chamber 108, as shown in FIGURE 40. This incoming trash, will of course, rest upon the already compressed block of trash in the bottom of the compacting chamber. When the photocell device 16 is again blocked for a sufficient amount of time as preselected by the setting on the time delay device 132, the ram will again descend and will powerfully compress the trash again.

After this operation occurs several different times, the height of the block of compressed trash will gradually increase. As shown in FIGURE 4d, for purposes of illustration, the compressed blocks of trash are individually crosssectioned. However, it will be understood that in actual operation, the trash will not be compressed into separate blocks, but instead, will form one compressed bale which gradually increases in height. When, at last, the height of such a bale reaches that shown in FIGURE 4, the trash will eventually back up within the trash receiving chamber high enough to break the light beam of the photocell means 18. That is, even if the ram were to continue to operate due to the fact that the photocell 16 was blocked, the height of the bale itself would prevent the incoming trash from being fully transferred from the trash receiving chamber 42. As a result, when this occurs, and the photocell 18 is blocked, the switch 138 is closed. This sends current to the time delay device 140 which is preferably preset for a delay interval of two minutes. After this delay interval elapses, the current will be transmitted to the solenoid 58 to cause the same to pivot the hook lever 60 to release the door 50. The counterweights will then cause the door 50 to move across the top of the trash directing means thereby blocking the inlet opening 28 and hence preventing any further trash from the trash chute from dropping into the trash receiving chamber 42. Instead, such trash will merely build up within the trash chute on top of the door 50. Simultaneously with energization of the solenoid 58, the alarm 142 is operated. This alarm operation signals a janitor or maintenance man or other operator to advise him that the bale has reached the proper height. When the maintenance man or operator arrives inresponse to the signal from the alarm 142, he can deactivate such alarm by opening the switch 144. He can then open the auxiliary door 94 to manually scoop the trash into the top of the baling means 10. Then, by closing the switch 134, he can manually operate the baler means to compress this last amount of trash. This operation will succeed in emptying the trash receiving chamber 42 and in compressing all of the trash within the compacting chamber 108. Since the door 50 is now closed, it prevents any further trash from dropping into the trash receiving chamber. At this time, the janitor can roll the baling means along the tracks 78 and out of engagement with the trash directing means 10. The operator can then open the doors 86 and 90 on opposite sides of the baling means to fully expose the bale which is now sitting in self-sustained form within the compacting chamber. If desired, he can tie or bind the bale with wire, rope or other similar means. He then pushes the bale out of the compacting. chamber so that the same comes completely free from the baling means 14. If an incinerator is provided in the building, the janitor can throw the entire bale into such incinerator for immediate disposal. On the other hand, if no such incinerator is present, he can merely wrap the bale with a plastic film sheet to prevent odors from escaping and to assure that no bugs or rodents can get at the bale while the same is stored. Bales which have been so wrapped in these plastic sheets, can be stored for from one to several days until a trash truck arrives. Then, the Wrapped bales can merely be thrown upon the trash truck and suitably disposed of by the trash company.

After the operator has completed removal of the bale, he closes the doors on the baling means and moves the same back to assembled juxtaposed relation with the trash directing means. He then manually pulls the door 50 open, through a pulling force exerted on the handles 64, and resets the operating circuit. As the door 50 is pulled open, the trash which has accumulated in the trash chute 12 can drop freely into the trash receiving chamber 42 and from there can transfer into the compacting chamber 108. The foregoing cycle can then be repeated. It will also be understood that if, for one reason or another, the janitor or maintenance man desires to empty some trash directly into the baler while the same was assembled to the trash directing means 10, he can do so merely by Opening the auxiliary door 94.

After reading the foregoing detailed description, it should be apparent that the objects set forth at the outset of the specification have been successfully achieved by the present invention.
